Emotions and coping strategies during the COVID-19 quarantine in 5-year-old children in the Pampahasi area of La Paz city

2025-04-07T19:02:23+00:00

The COVID-19 pandemic had a high cost on the global population, and mental health was no exception. The general objective of the research was to describe the emotions and coping strategies presented by 5-year-old children living in the Pampahasi area of La Paz city during the COVID-19 quarantine. The theoretical framework is based on the cognitive model of psychology. The research corresponds to the interpretative paradigm, qualitative approach, and inductive and visual methods; drawing and semi-structured interviews were the data collection techniques. The results show that children felt happiness, sadness, longing, anger, and fear; they coped with the COVID-19 quarantine using problem-focused and emotion-focused strategies. It is concluded that the positive emotion of happiness is linked to the affection and attention of the family. Problem-focused coping strategies were more effective. Based on the results, resources are proposed to be applied to the WhatsApp group of Parents to improve the emotions and coping strategies of children during a possible future quarantine.

Thought, practice, and sexual life of young people at UNIVALLE for the construction of their identity

2025-04-07T19:15:41+00:00

The thoughts, practices, and sexual lives of young people, while being a common and highly important topic within society, do not receive the continuity or follow-up they require. This issue transitions from a personal level, such as the construction of identity and acceptance or tolerance, to a complex context that impacts the very institutions of society in a highly globalized world that changes with trends and influences, particularly in values and morality, driven by social media. Therefore, this research aims to describe variables regarding perceptions and preferences in the area of sexuality among young people, following a descriptive study through the application of surveys to a selected population, using a non-probabilistic cluster sampling method. The results obtained allow for the observation of a trend towards greater tolerance and sexual freedom, albeit still with some confidentiality regarding their families and religion.

Building capacities through technological and scientific networks

2025-04-07T19:10:06+00:00

In this digital context, with unrestricted access to social networks, platforms, and applications, the user has control and autonomy in their daily use. However, this does not imply that new technological skills have improved individual capacities or overcome the limits of scientific knowledge in our society. This assertion comes from research on the academic impact of access to new information and communication technologies on the development of university students' competencies. The research question focuses on the academic impacts of these technologies on students. A mixed research method was used, combining qualitative and quantitative approaches, with samples of expert and non-probabilistic subjects.

The results show that access to digital media does not guarantee a real utilization of technological advancements, that there is no widespread development of students' educational capacities, and that students do not perceive the importance of building technological networks. Therefore, before incentivizing the formation of technological and scientific networks, it is necessary to include both teachers and students for proper learning of these new competencies.

The article presents research focused on the optimization of energy and water consumption in towers closed circuit cooling, specifically in the redesign of a tower used by the company Vinto Metallurgical. The operating principles of these towers and the importance of reducing resource consumption. For this, a mathematical model is proposed that is based on energy balances and of mass, including equations that describe the variation in temperature and humidity of air and water in the system, as well as the boundary conditions necessary for its analysis. Furthermore, an approach is addressed to solve dimensionless differential equations related to the operation of towers cooling. Numerical methods are used, such as the shot method and the Runge-Kutta method of fourth order, implemented in the EES software, to determine unknown variables such as temperature of cooling water and specific humidity. The operating conditions of the tower are analyzed, considering factors such as dry and humid temperature, and constant load scenarios and variable. The results indicate that operating conditions are influenced by environmental factors. and that an adequate control system can optimize the energy performance of the tower. It is concluded that Variability in load and environmental conditions have a significant impact on fuel consumption. energy and the flow of evaporated water, which highlights the need for optimization strategies in processes industrial refrigeration.

Immediate dental sealing in oral rehabilitation at the UNIVALLE Dental Clinic in the city of La Paz

2025-04-07T19:32:04+00:00

In oral rehabilitation, there are many methods by which a dental piece can be preserved. Several studies show us that in order to properly use materials for oral rehabilitation, various protocols must be followed. As researchers, we will demonstrate why it is so important to use adhesives correctly when applied to the enamel and dentin surfaces. To observe these components, biologically compatible materials and optical instruments were used. With the materials used, we were able to visualize the interaction of the adhesive with peripheral dentin sealing, achieving a good seal of the adhesive with the dental tissues
